PF-562271 HCl is a potent, ATP-competitive, and reversible inhibitor of focal adhesion kinase (FAK, IC50 1.5 nM) and proline-rich tyrosine kinase 2 (Pyk2, IC50 14 nM). By blocking FAK autophosphorylation, PF-562271 inhibits downstream focal adhesion signaling, suppressing tumor cell migration, invasion, and proliferation across multiple cancer types, while exhibiting broad selectivity against other protein kinases.

Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
- Preheat media/saline to 37°C.
- Mix rapidly (pipette/vortex) upon addition.
- For complex mixes, always add the aqueous phase last.
- Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
Pre-aliquoted for Longevity: Solid-state aliquots offer significantly longer shelf life compared to stock solutions, ensuring maximum stability for every use.
